Thanks to the wonder of 3D printing, scientists have managed to create a real, working heart — out of a patient's own cells.

The heart measures about 2.5 centimeters long, which is around "the size of a rabbit's heart," Bloomberg reports. Although it's certainly too small to function as a human heart, it was printed using an ink made from a patient's biological materials, meaning it's an exact match for the patient in question.

A process like this, which converts fatty tissue from the patient into stem cells and the so-called "bio ink," could be used to print tissue to patch diseased hearts, or even replace a heart entirely. Because it's made from each individual patient, the risk of an organ rejection is greatly lessened, said Tal Dvir, a professor at Tel Aviv University who directed the project.

This medical breakthrough was published on Monday in the journal Advanced Science, where it laid out the possibility of "personalized tissues and organs" being custom-printed for patients who need them, rather than those patients relying on organ donors.

While the tiny version of the heart took about three hours to print, it's estimated that a human-sized one could take a full day, and would require many more cells from the patient. But it's worth exploring whether these 3D-printed tissues could practically serve to replace a diseased heart with "something that works," Dvir said.

President Trump's North Carolina rally was panned by two people close to him: his wife, first lady Melania Trump, and his daughter, Ivanka Trump.

Both women, as well as Vice President Mike Pence, told Trump they didn't like how the crowd started chanting "Send her back!" after he attacked Rep. Ilhan Omar (D-Minn.), people with knowledge of the matter told CBS News on Thursday. Omar, a naturalized citizen who was born in Somalia and came to the U.S. as a young refugee, was one of the four Democratic congresswomen of color he tweeted needed to "go back" to their original countries.

Trump didn't try to stop the chanting, which lasted for about 13 seconds, or admonish the crowd. When asked about the incident on Thursday, Trump told reporters he "felt a little bad about it," and insisted he "started speaking very quickly" in order to get the crowd under control.

Earlier in the day, Trump discussed the chant with his inner circle, CBS News reports, and shared his concerns that if he backed down, his supporters would be upset. Catherine Garcia

Capitol Police arrested 70 people on Thursday during protests against the Trump administration's immigration policies.

The protesters were arrested inside the Russell Senate Office Building, with Capitol Police saying they were unlawfully demonstrating in the rotunda. Thursday was the Catholic Day of Action to oppose immigration policies like detaining migrants in overcrowded facilities without adequate necessities. The Sisters of Mercy traveled from Chicago to Washington, D.C., for the protests, and one nun, 90-year-old Sister Pat Murphy, was arrested.

The situation in immigrant detention centers is "immoral," Murphy told ABC News during a phone interview. "These are our brothers and sisters and they are part of the human family," she said, adding, "I mean, any person with any human compassion would reach out. What is going on is, it's just abominable. It's a horrific situation that's happening right now." Murphy, who has been with Sisters of Mercy for 71 years, said it's not fair that people are "being punished because our immigration system is broken, it's shattered, it doesn't exist."

President Trump will most likely nominate attorney Eugene Scalia to be the next Labor secretary, three people familiar with the matter told Politico.

Scalia is the son of the late Supreme Court Justice Antonin Scalia, and is a partner at the law firm Gibson, Dunn & Crutcher. In 2006, he represented Walmart in the retail giant's fight against a Maryland law that would have forced the company to spend more money on employee health care.

Last week, Labor Secretary Alexander Acosta stepped down following outrage over a 2008 plea deal he arranged with sex offender Jeffrey Epstein in Florida. Acosta's deputy, Patrick Pizzella, will step into the role on Friday. Catherine Garcia

The Environmental Protection Agency announced on Thursday it will not ban the use of chlorpyrifos, a pesticide associated with health problems in children.

During the Obama administration, the EPA produced scientific studies showing chlorpyrifos could damage brain development in children and prohibited its use, but in 2017, Scott Pruitt, then the agency's administrator, reversed course. This led to a legal battle, and in April, a federal appeals court told the EPA it had to make a final decision on the ban by July. In a statement, the agency said there is not enough data to show that an unsafe amount of pesticide residue is left in or on treated foods.

Sold under the name Lorsban, chlorpyrifos cannot be used in homes, but can be used by farmers, who spray it on more than 50 nut, fruit, vegetable, and cereal crops, The New York Times reports. Since the legal battle began, several states, including California and New York, have announced they are looking into banning chlorpyrifos. Catherine Garcia

Words can't adequately prepare you for your first glimpse at the Cats movie.

Universal Pictures on Thursday debuted the highly-anticipated first footage from its upcoming musical adaptation after months of teases about Taylor Swift's attending of "cat school" and the film's supposedly revolutionary use of, as the filmmakers describe it, "digital fur technology." And, well, here it is.

From start to finish, the trailer is a wild ride that doesn't even attempt to ease viewers into how surreal literally every character in the film looks. That online reactions to the initially funky-looking CGI Genie in Aladdin and the extremely distressing new Sonic the Hedgehog don't even hold a candle.

Cats' cast includes, believe it or not, Taylor Swift, Jennifer Hudson, James Corden, Ian McKellen, and Judi Dench, who discussed their experience making the film in a recent behind-the-scenes reel featuring such quotes as "these are people but they're cats ... there is nothing else like it." Indeed, there isn't. Take a deep breath and watch the trailer below. Brendan Morrow

Tom Cruise still has that need for speed, even three decades later.

At San Diego Comic-Con on Thursday, Cruise made an unannounced appearance following a Terminator: Dark Fate panel to reveal the first trailer for the long-awaited Top: Gun Maverick, a follow-up to the 1986 original that's set for release next year. The footage, which dropped online shortly after its Comic-Con debut, shows off Cruise's return as Maverick and some seriously impressive-looking flying sequences.

Cruise, who in recent years has infamously done his own, increasingly insane stunts for the Mission: Impossible franchise, promised the Comic-Con audience similar authenticity in Maverick, saying, "Everything you see in this film, obviously, it's for real," Variety reports. "We're working with the Navy. All of the flying that you see in this picture, everything is real." He also described the movie as a "love letter to aviation."

Top Gun: Maverick will hit theaters on June 26, 2020, and Cruise said Thursday that after a 34 year wait, "I felt it was my responsibility for me to deliver for you." Watch the trailer below. Brendan Morrow

The U.S. Navy has "destroyed" an Iranian drone in the Strait of Hormuz, President Trump announced Thursday afternoon.

The U.S.S. Boxer was sailing in the strategic strait when the drone came within 1,000 yards of it and ignored "multiple calls to stand down," Trump told reporters. It then took "defensive action" and used electronic jamming to down the drone, Trump continued.

The attack comes after Iran's Islamic Revolutionary Guard Corps on Thursday claimed responsibility for seizing a foreign tanker that went missing this past weekend in the Strait of Hormuz, The Washington Post notes. It's the latest international incident in the waterway that connects the Persian Gulf with the rest of the world, and also comes amid rising tensions between the U.S. and Iran. Iran shot a U.S. drone in that area last month, but while America says it was in international airspace, Iran claimed it was flying in Iranian territory. Kathryn Krawczyk
